ASUS has added 10-phase DIGI+ VRM digitally regulated power delivery with 30% noise reduction, working in tandem with durable Super Alloy Power components that last 2.5 longer than reference. Users can tap the greater overclocking and overvolting capabilities of the card through both the hardware-level VGA Hotwire and the software-level GPU Tweak utility. Also released is the ASUS GeForce GTX 680 DirectCU II OC edition, with a 1019 MHz core capable of a 1084 MHz boost clock. This card uses the same DirectCU II cooler and PCB as the TOP version.
